Electricity Usage Calculator

Cost = (Watts × Hours Used × Electricity Rate) / 1000. For example, a 1,500W space heater running 8 hours at $0.12/kWh costs $1.44/day or about $43/month.

Central AC (3,000-5,000W), electric water heater (4,500W), clothes dryer (3,000W), space heater (1,500W), and oven (2,500W) are typically the biggest energy consumers.

Switch to LED bulbs, use a programmable thermostat, unplug unused devices, run full loads in washer/dryer, air dry clothes, and upgrade to Energy Star appliances.
